经过评估，专家小组得出结论，该食品酶在预期的使用条件下不会引起安全问题。部分原文报道如下：
The food enzyme endo-1,4-β-xylanase (EC 3.2.1.8) is produced with the genetically modified Trichoderma reesei strain NZYM-ER by Novozymes A/S. The safety of this food enzyme was evaluated previously, and it did not give rise to safety concerns when used in four food manufacturing processes. Subsequently, the applicant has requested to extend its use to include three additional processes. In this assessment, EFSA updated the safety evaluation of this food enzyme when used in a total of seven food manufacturing processes. As the food enzyme–Total Organic Solids (TOS) are removed in four processes, the dietary exposure to the food enzyme–TOS was estimated for the remaining three food manufacturing processes. It was calculated to be up to 0.092 mg TOS/kg body weight (bw) per day in European populations. When combined with the no observed adverse effect level previously reported (1051 mg TOS/kg bw per day, the highest dose tested), the Panel derived a margin of exposure of at least 11,424. based on the revised exposure estimation, the newly derived margin of exposure and the previous evaluation, the Panel concluded that this food enzyme does not give rise to safety concerns under the revised intended conditions of use.
